To all whom it may concern:

Be it known that I, THOMAS PARKER, M. I. C. E., a subject of the King of Great Britain and Ireland, residing at 1*, Chapel have "invented certain new and useful Imrovements in Retorts for the Distillation of oal and other Carbonaceous Substances, of

which the following is a specification.

This invention relates to the distillation of coal and other carbonaceous substances more particularly for the production of a partially coked fuel under'the conditions and in the manner described in the specification of the. British patent granted to me No. 143-65/06.

The invention has for its object to r'ovide a retort or still of such shape as wil insure the convenient charging of the coal and its Withdrawal after treatment without possibil ity of the charge han ing retort or still and 0 such shape that the charge may be conveniently and uniformly heated from without.

The invention is illustrated in the accompanying drawings in which Figure 1 is a front sectional elevation of a retort or still provided according to the invention; Fig. 2 is a'section on the line as (Fig. 1)

According to the invention I tort or still a advantageously o rovide a reoblong secing mouth I) atthe top of relatively small cross sectional dimensions to the discharging mouth 0 at the bottom of relatively large cross sectional dimensions. A number of such retorts are capable of being vertically or diagonally mounted in a common setting or so that heat may be uniformly and completely applied-around them. According to the invention moreover I provide still a, to close the discharging mouth 0 and to carry the burden of the charge. This bottom .cover plate d is hinged loosely upon; a

spindlee conveniently carried on the underface of the retort or still a. and means are provided comprising a rod f advantageously passing up alongside'one of the walls of the retort or still a, with means 0 erated from above the retort or still a by w may be lifted or lowered for the lifting or lowering of the'lower cover plate d upon the spindle e aforesaid upon which it is mountedto hinge. These means conveniently consist to the sides of the p ich the-rodf in the provision of screw threads 9 upon the extremity of the rod f aforesaid which projects above the upper cover plate h of the retort or still, which cover plate h is advantageously bolted to the top of the still a, the rod f advantageously passing through a stuffing box & mounted upon the cover plate h or integral with it by which a tight joint may be insured. The screwed extremity of the rod f protrudes beyond the stuffing box *5 and the internally screwed boss 9' of an operating hand wheel 7c is mounted thereon.

The upper extremity of the rod f has mounted u on it and beneath the operating hand whee l k a sleeve or collar 1 against which a spiral spring mabuts which encircles the rodf in a osition above the stufiin box '5 aforesaid, t e opposite extremity o the s iral spring m abutting against the cover ate or gland n of the stuffing box and thus exercising ressure tending to force the sleeve or co ar Z and operating hand wheel k u wardlyso that the pressure imposed on t e rotation of the screw g'for the purpose of lifting the lower cover late cl may be in fact transmitted throu h t 1e spring m and thus the lower cover plate cl may be 'closed by elastic pressure, and compensation provided for the contraction and expansion of the rod f. a a

I prefer to connect the lower extremity of the roll f to the upper face of the-lower cover plate d at a point as nearly as convenient and effective to that side of the still or retort at which the lower cover plate (1 is hinged and I divert the rod towards its lower extremity as shown at 0 so that it may pass up the retort or still in close proximity to the wall thereof.

,1 may mount above or upon the gland two or other number of stops, or a ring to act as a stop, or a ring p carryingan internal annular 'roove g within which the sleeve or collarl efore referred to may have restricted longi tudinal play for the purpose described, such ring may be carried by means of two or more vertical bolts 1" mounted upon the top flange of the stufling box 1' aforesaid.

I prefer to provide the charging chute s of cylindrical or other form and to mount it uponthe ,u stilla whic 1 at the same time may serve as an uptake for the gases and vapors generated during the process of distillation, which vapors and gases may pass out therefrom through a lateral hole t of which two may be previded eppesite poeitiene 30 that time when a member ef reterts are Insulated side hy sideieseries, they may eenn Jeri together with their outrets in line and there? the rapee end gasee meg di the euti f the stifi 0r retert end 015' the series or Otherwise. i removable id 2:. 01' cover plate of any suitable form may be mounted ween tee upper aperture ef the ey- Kindricei eBa-rgieg enute and is preferably previcled with; conical face to eorrespend with e conical seat '5 provided around the aperture efereseid.

3; claim as my inventien and desire to secure by Letters Patent ie:

1. A retort having a hinged bottom plate a reel eermeeted to said plate, a spring engaga red connected to said plate, said red hat ing a screw threaded up e? end, a nut engaging with said serew t needed end and a sorted sprmg between the nut and a. part of the retort.
